GCJ 3.1: will generated code run on almost all versions of Windows?

[Jocelyn Paine <popx at ifs dot org dot uk>]

I'm writing a Java application which is to run on Windows, and I'd like to
give away copies at a conference for people to try out. The audience won't
know anything about installing their own JVMs etc., so using GCJ 3.1 to
generate a single .exe file that can be installed and run without needing
anything else seems ideal.

I won't know in advance which Windows users will have: 95, 98, NT, 2000,
XP or ME. As long as I avoid Windows NT 3.5 and below, and 3.11 (as
indicated by the MinGW page at http://www.mingw.org/mingwfaq.shtml), will
I really be able to generate just one file, a .exe, and guarantee it will
run on any of these? I don't know why, but somehow, the name 'Microsoft'
stirs suspicions that things can't be so easy.

(I'm actually writing the app in Per Bothner's Kawa dialect of Scheme,
which compiles to JVM code. That shouldn't matter, though, I hope.)
